3 EASY SCIENCE EXPERIMENTS TO TRY AT HOME FOR KIDS

1. MAKE YOUR OWN VOLCANO!This is a classic experiment in which a chemical reaction can create the appearance of a physical volcano eruption. A chemical reaction between the vinegar and the bicarbonate of soda creates a gas called carbon dioxide. Carbon dioxide is the same type of gas used to make the carbonation in fizzy drinks. What happens if you shake up a can of Coke? The gas gets very excited and tries to spread out. There is not enough room in the bottle for the gas to spread out so it leaves through the opening very quickly, causing an eruption!

To make the volcano, you can use play dough or if you’d rather your volcano made less inside mess, use a mound of sand outside.

Play dough is fun, easy and cheap to make your own.

You will need:1 large bowl1 cup of plain flour1/4 cup of hot water1/3 cup of saltFood colouring2 Tbsp of cooking oil

Step 1: In the bowl, mix the flour and salt. Step 2: Add the hot water and mix until all stickiness is gone. Step 3: Add 1 drop of food colouring and mix it into your mixture to brighten your doughStep 4: Add the oil, mix it in well and get playing!

Note: If the mixture is too sticky add more flour, and if it’s too dry add more water – just a tiny bit at a time.

2. MAGIC MILK EXPERIMENTHave you ever done the Magic Milk experiment? It's super fun science even for adults. Some very unusual interactions take place when you mix a little milk, food colouring, and a drop of dishwashing liquid.

The secret of the rainbow colours is in the chemistry of that tiny drop of soap. Like other oils, milk fat doesn’t dissolve in water. When soap is mixed in, however, the fun begins. The molecules of the fat bend, roll, twist, and swirl in all directions as the soap molecules race around to join up with the fat molecules. During all of this, the food colouring molecules are bumped and shoved everywhere, providing an easy way to observe all the invisible activity. As the soap becomes evenly mixed with the milk, the action slows down and eventually stops. Add another drop of soap to start the process again.

3. WALKING WATER EXPERIMENTIf you are looking for simple science to do with the kids and something that will really amaze them, this is definitely one to try. You’ll only need a few simple supplies that you probably already have around the house.

How does it work? The water appears to defy gravity, but,in reality, it moves because the paper towel has many tiny spaces. The water fills these tiny spaces and moves along the paper. The adhesive forces between the water and the paper towel are stronger than the cohesive forces inside the water. As a result, the water 'walks up' and across the paper towel out of one glass and into another.
